Abstract
A threshold signature scheme with fault-tolerance which is proposed by X.L. Zhang is analyzed, and it is pointed out that the dishonest internal participants can forge the signatures of the other participants. An improved threshold signature scheme with fault-tolerance is proposed. The new scheme can resist insider attacks effectively.
